Write the mechanism of aicd catalysed dehydration of ethanol to ethane.

Text Solution

Verified by Experts

(a) The mechanism of dehydration of ethanol involves the following steps :
Step 1 : Formation of protonated alcohol.

Step 2: Formation of carbocation : It is the slowest step and hence, the rate determing step of the reaction.

Step 3: Formation of ethane elimination of a proton.

(b) Phenol is more acidic than alcohol.
